What is a common sign of drowsy driving?

Frequent yawning or difficulty focusing is a well-documented indication of drowsy driving. When a driver is feeling tired, the body's natural response often includes yawning, which is an involuntary reaction intended to increase oxygen intake and alertness. Difficulty concentrating or staying focused on the road is another critical sign, as fatigue negatively impacts cognitive functions and reaction times.

In the context of road safety, recognizing these signs is essential because drowsy driving can lead to delayed reaction times, impaired judgment, and ultimately increase the risk of accidents. Drivers who notice these symptoms in themselves or others should take immediate measures, such as pulling over to rest or switching drivers if possible, to ensure safety on the road.
